Tomography test phantom JASZCZAK

for nuclear imaginggeneral purpose

Overview
The JASZCZAK phantom for SPECT delivers consistent information on the performance of any SPECT or PET system. Multiple performance characteristics of SPECT systems using a gamma camera are evaluated from a single scan of the phantom. SPECT phantoms are available in two models: the Deluxe model for high-definition cameras and the Standard model for lower-resolution systems.

Phantom applications

• Evaluation of system performance at the level of collimator, artifacts, calibration and reconstruction parameters
• Acceptance testing
• Highly flexible and "flaccid" construction
• Routine quality assurance and quality control
• Assessment of centre-of-rotation error
• Evaluation of non-uniformity artifact
• Assessment of gantry rotation variations on spatial resolution
• Evaluation of reconstruction filters on spatial resolution
• Evaluation of attenuation and scatter compensation
• Volume sensitivity for a single slice
• Total system volume sensitivity
• Lesion detectability
